1. An assembly for an aircraft propulsion system, comprising:
an open propulsor rotor configured to rotate about a rotational axis; and
an open guide vane structure axially next to the open propulsor rotor, the open guide vane structure including a plurality of open guide vanes arranged circumferentially about the rotational axis, and the plurality of open guide vanes comprising a first open guide vane;
the first open guide vane comprising a first vane leading edge, a first vane trailing edge and a fixed first vane chord length measured from the first vane leading edge to the first vane trailing edge, and the first open guide vane configured to translate axially along the rotational axis.
